✦ Synopsis

Dynamic behaviour is essential in the analysis of railway bridges and trains namely on high speed tracks. The action of railway traffic on bridges is performed by two different methodologies: in the first the train is considered as a set of moving masses, being the effects of the moving forces and masses implied; in 1:he second both the structural behaviour of the train and the interaction with the bridge are involved. Based on a real case, the effect of some parameters are analysed in this paper: characteristics of stiffness .and mass of the bridge, stiffness of the train, bridge span and track irregularities. The main aim is to evidence the importance of these parameters in order to investigate the structural behaviour of the bridge a.nd the comfort at the train.

## Abstract Vehicle, track and bridge are considered as an entire system in this paper. Two types of vertical vehicle model are described. One is a one foot mass–spring–damper system having two‐degree‐of‐freedom, and the other is four‐wheelset mass–spring–damper system with two‐layer suspension sys

This article presents an integrated model for the computation of vehicle–track interaction and the ground vibrations of passing trains. A combined finite element and boundary element method is used to calculate the dynamic compliance of the track on realistic soil whereas multi-body models are used
